I did some research before buying them, they are supposed to be just as good as new tires, and just as safe. but we now how that "supposed to be" thing goes. I think the lighter weight of the kia will be a benefit to this idea. but they are warrantied for 2 years or 24,000 miles.

I guess I will find out first hand!

I hope your friend didn't get to banged up, sounds like a rough ride though!
